Depending on the cause, your condition may be diagnosed and/or monitored using other tests such as calcium, phosphorus, parathyroid hormone, vitamin D, or bone markers (a group of tests used to measure bone formation and bone resorption).
Because the flu vaccine is produced by private manufacturers, its availability depends on when production is completed. For the 2015-2016 flu season, manufacturers have indicated shipments are likely to begin in July or August and continue throughout September and October until all vaccine is distributed. Doctors and nurses are encouraged to begin vaccinating people as soon as flu vaccine is available in their areas.
Adults and children usually receive the injection in the upper arm, and infants receive it in the upper thigh. The vaccination is usually given in the time from September to November when the number of cases of influenza virus begins to increase (the start of flu season).
